This application claims the benefit of U.S. Provisional Application No.61/000,515, filed 26 Oct. 2007, which specification is herebyincorporated here in by reference in its entirety.

FIELD OF THE INVENTION

The invention relates generally to the field of pharmaceutical agentsand, more specifically, to pharmaceutically active compounds,pharmaceutical compositions and methods of use thereof, to treat variousdisorders, including TNF-α, IL-β, IL-6 and/or IL-8 mediated diseases andother maladies, such as inflammation and pain, via the regulation of theactivity of the p38 mapkinase protein.

BACKGROUND OF THE INVENTION

Protein kinases represent a large family of enzymes, which catalyze thephosphorylation of target protein substrates. The phosphorylation isusually a transfer reaction of a phosphate group from ATP to the proteinsubstrate. Common points of attachment for the phosphate group to theprotein substrate include, for example, a tyrosine, serine or threonineresidue. For example, protein tyrosine kinases (PTKs) are enzymes, whichcatalyze the phosphorylation of specific tyrosine residues in cellularproteins. Examples of kinases in the protein kinase family include,without limitation, ab1, Akt, bcr-ab1, Blk, Brk, Btk, c-kit, c-Met,c-src, c-fms, CDK1, CDK2, CDK3, CDK4, CDK5, CDK6, CDK7, CDK8, CDK9,CDK10, cRaf1, CSF1R, CSK, EGFR, ErbB2, ErbB3, ErbB4, Erk, Fak, fes,FGFR1, FGFR2, FGFR3, FGFR4, FGFR5, Fgr, flt-1, Fps, Frk, Fyn, Hck,IGF-1R, INS-R, Jak, KDR, Lck, Lyn, MEK, p38, PDGFR, PIK, PKC, PYK2, ros,tie, tie2, TRK, Yes, and Zap70. Due to their activity in numerouscellular processes, protein kinases have emerged as importanttherapeutic targets.

Protein kinases play a central role in the regulation and maintenance ofa wide variety of cellular processes and cellular function. For example,kinase activity acts as molecular switches regulating inflammatorycytokine production via various pathways. Uncontrolled or excessivecytokine production has been observed in many disease states, andparticularly in those related to inflammation.

The p38 protein kinase has been reported to be involved in theregulation of inflammatory cytokines. Interleukin-1 (IL-1) and TumorNecrosis Factor α (TNF-α) are pro-inflammatory cytokines secreted by avariety of cells, including monocytes and macrophages, in response tomany inflammatory stimuli (e.g., lipopolysaccharide—LPS) or externalcellular stress (e.g., osmotic shock and peroxide).

Elevated levels of TNF-α over basal levels have been implicated inmediating or exacerbating a number of disease states includingrheumatoid arthritis; osteoarthritis; rheumatoid spondylitis; goutyarthritis; inflammatory bowel disease; adult respiratory distresssyndrome (ARDS); psoriasis; Crohn's disease; allergic rhinitis;ulcerative colitis; anaphylaxis; contact dermatitis; asthma; muscledegeneration; cachexia; Reiter's syndrome; type II diabetes; boneresorption diseases; graft vs. host reaction; ischemia reperfusioninjury; atherosclerosis; brain trauma; multiple sclerosis; cerebralmalaria; sepsis; septic shock; toxic shock syndrome; fever, and myalgiasdue to infection. HIV-1, HIV-2, HIV-3, cytomegalovirus (CMV), influenza,adenovirus, the herpes viruses (including HSV-1, HSV-2), and herpeszoster are also exacerbated by TNF-α.

TNF-α has been reported to play a role in head trauma, stroke, andischemia. For instance, in animal models of head trauma (rat), TNF-αlevels increased in the contused hemisphere (Shohami et al., J. Cereb.Blood Flow Metab. 14:615 (1994)). In a rat model of ischemia wherein themiddle cerebral artery was occluded, the levels of TNF-α mRNA of TNF-αincreased (Feurstein et al., Neurosci. Lett. 164:125 (1993)).Administration of TNF-α into the rat cortex has been reported to resultin significant neutrophil accumulation in capillaries and adherence insmall blood vessels. TNF-α promotes the infiltration of other cytokines(IL-1, IL-6) and also chemokines, which promote neutrophil infiltrationinto the infarct area (Feurstein, Stroke 25:1481 (1994)).

TNF-α appears to play a role in promoting certain viral life cycles anddisease states associated therewith. For instance, TNF-α secreted bymonocytes induced elevated levels of HIV expression in a chronicallyinfected T cell clone (Clouse et al., J. Immunol. 142:431 (1989)).Lahdevirta et al., (Am. J. Med. 85:289 (1988)) discussed the role ofTNF-α in the HIV associated states of cachexia and muscle degradation.

TNF-α is upstream in the cytokine cascade of inflammation. As a result,elevated levels of TNF-α may lead to elevated levels of otherinflammatory and proinflammatory cytokines, such as IL-1, IL-6, andIL-8. Elevated levels of IL-1 over basal levels have been implicated inmediating or exacerbating a number of disease states includingrheumatoid arthritis; osteoarthritis; rheumatoid spondylitis; goutyarthritis; inflammatory bowel disease; adult respiratory distresssyndrome (ARDS); psoriasis; Crohn's disease; ulcerative colitis;anaphylaxis; muscle degeneration; cachexia; Reiter's syndrome; type IIdiabetes; bone resorption diseases; ischemia reperfusion injury;atherosclerosis; brain trauma; multiple sclerosis; sepsis; septic shock;and toxic shock syndrome. Viruses sensitive to TNF-α inhibition, e.g.,HIV-1, HIV-2, HIV-3, are also affected by IL-1. Thus, there is a need toregulate the levels of cytokines, including IL-1, IL-6, and IL-8 andTNF-α, as a means of regulating inflammatory conditions and diseasesrelated thereto.

Antagonism of TNF-α has been reported to be beneficial for treatinguveitis (Reiff et al, A&R 44:141-145 (2001)); Sepsis (Abraham, Lancet,351:929 (1998)); Systemic Lupus Erythrematosis (SLE) (Aringer, A&R,50:3161 (2004)); Graft vs Host Disease (Couriel, Curr. Opinion Oncology,12:582 (2000)); Polymyositis and Dermatomyositis (Labiache,Rheumatology, 43:531 (2004)); Type II diabetes (Ruan, Cytokine GFReview, 14:447 (2003)); Sjogren's disease (Marriette, A&R, 50:1270(2004)), Sarcoidosis (Roberts, Chest, 124:2028 (2003)); Wegener'sgranulomatosis (WGET, New England J. Med., 352:351 (2005)) and post MIcardiac dysfunction (Sugano et al, Mol. Cell. Bioch., 266:127 (2004)).In addition, TNF-α has been reported to play a role in SAPHO, periodicfever, relapsing polychrondritis, multicentric reticulohistiocytosis,macrophage activation syndrome, Hyper IgD syndrome, familial Hibernianfever, Pyoderma gangrenosum, Cochleovestibular disorders, Cicatricalpemphigoid, Herniated intervertebral disc diseases, amyloidosis, CINCAsyndrome, myelodisplastic syndrome, alcoholic hepatitis, andendometriosis. Finally, indications which have already been approved foran agent which modulates TNF-α levels in the plasma, and/or otherpro-inflammatory cytokines, include without limitation, inflammatorybowel disease (IBD), psoriatis arthritis, ankylosing spondylitis andjuvenile RA.

TNF-α and IL-1 appear to play a role in pancreatic β cell destructionand diabetes. Pancreatic β cells produce insulin which helps mediateblood glucose homeostasis. Deterioration of pancreatic β cells oftenaccompanies type I diabetes. Pancreatic β cell functional abnormalitiesmay occur in patients with type II diabetes. Type II diabetes ischaracterized by a functional resistance to insulin. Further, type IIdiabetes is also often accompanied by elevated levels of plasma glucagonand increased rates of hepatic glucose production. Glucagon is aregulatory hormone that attenuates liver gluconeogenesis inhibition byinsulin. Glucagon receptors have been found in the liver, kidney andadipose tissue. Thus, glucagon antagonists are useful for attenuatingplasma glucose levels (WO 97/16442, incorporated herein by reference inits entirety). By antagonizing the glucagon receptors, it is thoughtthat insulin responsiveness in the liver will improve, therebydecreasing gluconeogenesis and lowering the rate of hepatic glucoseproduction.

In rheumatoid arthritis models in animals, multiple intra-articularinjections of IL-1 have led to an acute and destructive form ofarthritis (Chandrasekhar et al., Clinical Immunol Immunopathol., 55:382(1990)). In studies using cultured rheumatoid synovial cells, IL-1 is amore potent inducer of stromelysin than is TNF-α (Firestein, Am. J.Pathol., 140:1309 (1992)). At sites of local injection, neutrophil,lymphocyte, and monocyte emigration has been observed. The emigration isattributed to the induction of chemokines (e.g., IL-8), and theup-regulation of adhesion molecules (Dinarello, Eur. Cytokine Netw.,5:517-531 (1994)).

IL-1 also appears to play a role in promoting certain viral life cycles.For example, cytokine-induced increase of HIV expression in achronically infected macrophage line has been associated with aconcomitant and selective increase in IL-1 production (Folks et al., J.Immunol., 136:40 (1986)). Beutler et al. (J. Immunol., 135:3969 (1985))discussed the role of IL-1 in cachexia. Baracos et al. (New Eng. J.Med., 308:553 (1983)) discussed the role of IL-1 in muscle degeneration.

In rheumatoid arthritis, both IL-1 and TNF-α induce synoviocytes andchondrocytes to produce collagenase and neutral proteases, which leadsto tissue destruction within the arthritic joints. In a model ofarthritis (collagen-induced arthritis (CIA) in rats and mice),intra-articular administration of TNF-(either prior to or after theinduction of CIA led to an accelerated onset of arthritis and a moresevere course of the disease (Brahn et al., Lymphokine Cytokine Res.11:253 (1992); and Cooper, Clin. Exp. Immunol., 898:244 (1992)).

IL-8 has been implicated in exacerbating and/or causing many diseasestates in which massive neutrophil infiltration into sites ofinflammation or injury (e.g., ischemia) is mediated by the chemotacticnature of IL-8, including, but not limited to, the following: asthma,inflammatory bowel disease, psoriasis, adult respiratory distresssyndrome, cardiac and renal reperfusion injury, thrombosis andglomerulonephritis. In addition to the chemotaxis effect on neutrophils,IL-8 also has the ability to activate neutrophils. Thus, reduction inIL-8 levels may lead to diminished neutrophil infiltration.

Several approaches have been taken to block the effect of TNF-α. Oneapproach involves using soluble receptors for TNF-α (e.g., TNFR-55 orTNFR-75), which have demonstrated efficacy in animal models ofTNF-α-mediated disease states. A second approach to neutralizing TNF-αusing a monoclonal antibody specific to TNF-α, cA2, has demonstratedimprovement in swollen joint count in a Phase II human trial ofrheumatoid arthritis (Feldmann et al., Immunological Reviews, pp.195-223 (1995)). These approaches block the effects of TNF-α and IL-1 byeither protein sequestration or receptor antagonism.

Yet another approach to block the effect of TNF-α has been to modulatethe activity of the p38 kinase enzyme. For example, the PCT publication,WO 04/010995, published on Feb. 5, 2004, describes fused heteroarylderivatives for use as p38 kinase inhibitors in the treatment of I.A.rheumatoid arthritis; PCT publication, WO 2005/009937, published on Feb.3, 2005, describes 5-membered heterocycle-based P38 kinase inhibitors;U.S. Pat. No. 6,635,644, issued Oct. 21, 2003, describes fusednitrogen-containing bicyclic ring systems as p38 inhibitors; and U.S.Pat. No. 6,794,380, issued Sep. 21, 2004, describes amide derivatives asp38 inhibitors. However, there remains a need to find therapeutic agentswith improved properties with respect to regulating the levels ofpro-inflammatory cytokines, useful for the treatment of inflammatorydisorders and disease. Despite the attempts and efforts to findtherapeutics for inflammatory conditions, there remains a need todiscover and find novel, more effective, efficient and safe therapeuticagents to regulate the production and effects of pro-inflammatorycytokines, and treat conditions and disorders related to inflammation.

The phrase “effective amount” is intended to quantify the amount of eachagent, which will achieve the goal of improvement in disorder severityand the frequency of incidence over treatment of each agent by itself,while avoiding adverse side effects typically associated withalternative therapies. The effective amount may be administered to thesubject in a single dosage form or in multiple dosage forms. The term“effective dosage amount” is thus not limited to a single dosage form,such as a single tablet, but may be spread out over multiple tablets orother forms of the compound(s) of the invention.

The term “leaving groups” (also denoted as “LG”) generally refer togroups that are displaceable by a nucleophile. Such leaving groups areknown in the art. Examples of leaving groups include, but are notlimited to, halides (e.g., I, Br, F, Cl), sulfonates (e.g., mesylate,tosylate), sulfides (e.g., SCH₃), N-hydroxsuccinimide,N-hydroxybenzotriazole, and the like. Nucleophiles are species that arecapable of attacking a molecule at the point of attachment of theleaving group causing displacement of the leaving group. Nucleophilesare known in the art. Examples of nucleophilic groups include, but arenot limited to, amines, thiols, alcohols, Grignard reagents, anionicspecies (e.g., alkoxides, amides, carbanions) and the like.

Desirably-substituted chloro pyrazolo-pyridinones 6, (where R² inFormula I is H) may be made by the method generally described inScheme 1. As shown, an amino pyrazolo-ethyl carboxylate 3 may be madefrom the reaction of an appropriate substituted hydrazine 1 (or it's HClsalt) with ethyl(ethoxymethylene) cyanoacetate 2 under suitableconditions, including known, conventional reaction conditions. Pyrazole3 can then be reacted with excess acetic acid to acetylate the primaryamine group of compound 3. The acetylated-amino-group can then befurther functionalized, as desired, by deprotonation of the amine usinga sufficiently strong base, such as NaH as shown, and reaction of theanion with a desired R³ electrophilic species, such as an alkyl halideor acyl group (not shown), to afford intermediate 4. The methyl group ofthe acetyl function of compound 4 can be deprotonated using asufficiently strong base, such as LDA, to effect ring closure andprovide the corresponding hydroxyl pyrazolo-pyridinone intermediate 5.Intermediate 5 may be used directly to prepare compounds of Formulas Ior II using methods described herein or conventional, known methods.

Alternatively, the alcohol group of intermediate 5 may be converted tothe corresponding chloride compound 6, using known methods, such as withPOCl₃, under suitable conditions. Compound 6 is a useful intermediate inthe synthesis of compounds of the invention. Compound 6 is hereindesignated as “intermediate A.”

Desirably-substituted pyrazolo-pyridinone compounds 8, 10 and 12 ofFormulas I or II, (where X is NR⁴ for compounds 8 and 12, while X is Ofor compound 10, and R⁵ is an amide linker as shown) may be made bymethods A, B or C, each generally described in Scheme 2. As shown inMethod A, an amino-linked phenyl pyrazolo-pyridinone 8 may be made fromthe reaction of compound intermediate 6 with a desirably substitutedaniline 7 under suitable palladium reaction conditions, such as thosedescribed in scheme 2 above. For the purposes of exemplary compoundsdisclosed herein, this method is designated as Method A.

As shown in Method B, an ether-linked phenyl pyrazolo-pyridinone 10 maybe made from the reaction of compound intermediate 6 with a desirablysubstituted phenol 9 under suitable palladium reaction conditions, suchas those described in scheme 2 above. For the purposes of exemplarycompounds disclosed herein, this method is designated as Method B.Method B may also be applied to prepare compounds of Formulas I and IIwherein X is S. Alternatively, compound 10 may be prepared usingintermediate compound 5 and displacing a chloro-phenyl moiety (notshown) using similar palladium conditions.

As shown in Method C, an amino-linked phenyl pyrazolo-pyridinone 12 maybe made from the reaction of compound intermediate 6 with a desirablysubstituted aniline 11 under suitable palladium reaction conditions,such as those described in scheme 2 above. For the purposes of exemplarycompounds disclosed herein, this method is designated as Method C. Forpurposes of scheme 3 below, the phenyl shown in compounds 7, 9 and 11 isdesignated as a B ring. Such B ring is not limited to a phenyl as shown,but includes all rings as defined in Formulas I and II.

The B ring, as illustrated in scheme 3, is substituted by a linker groupR⁵. The R⁵ linker group, including an amino, a carboxyl, a sulfonyl, anamido or a urea linker, as defined herein in Formulas I and II, connectvarious substitutions, including R⁷ non-cyclic moieties or R⁷ and R⁸cyclic rings (generally designated and referred to in Scheme 3, andthroughout the specification, as the “A” group or “A” ring) to the “B”ring. This linker may be attached by various coupling methods asdescribed in Scheme 3. Each of the nine sub-schemes, numbered 1-9 aboveand described below, utilize the following meanings for (R)_(n), X, Nu⁻,E⁺ and m: (R)_(n) refers to n number of R⁶, R⁷ and R⁸ substitutionswherein n is an integer from 0-5; X refers generally to a “leavinggroup” (also referred to herein as “LG”) such as a halide (bromine,chlorine, iodine or fluorine), alkylsulfonate and other known groups(also see definitions herein); Nu⁻ refers generally to a nucleophilicspecies such as a primary or secondary amine, an oxygen, a sulfur or aanionic carbon species—examples of nucleophiles include, withoutlimitation, amines, hydroxides, alkoxides and the like; E⁺ refersgenerally to an electrophilic species, such as the carbon atom of acarbonyl, which is susceptible to nucleophilic attack or readilyeliminates—examples of suitable electrophilic carbonyl species include,without limitation, acid halides, mixed anhydrides, aldehydes,carbamoyl-chlorides, sulfonyl chlorides, acids activated with activatingreagents such as TBTU, HBTU, HATU, HOBT, BOP, PyBOP and carbodimides(DCC, EDC, CDI and the like), and other electrophilic species includinghalides, isocyanates, daizonium ions and the like; and m is either 0 or1.

The coupling of ring B to A, as shown as products in sub-schemes 1-9,can be brought about using various conventional methods to link ring Band A together. For example, an amide or a sulfonamide linkage, as shownin sub-schemes 2 and 4, and 7 and 9 where the Nu− is an amine,respectively, can be made utilizing an amine on either the B or A groupsand an acid chloride or sulfonyl chloride on the other of either the Bor A groups. The reaction proceeds generally in the presence of asuitable solvent and/or base. Suitable solvents include, withoutlimitation, generally non-nucleophilic, anhydrous solvents such astoluene, CH₂Cl₂, THF, DMF, DMSO, N,N-dimethylacetamide and the like,including solvent combinations thereof. The solvent may range inpolarity, as appreciated by those skilled in the art. Suitable basesinclude, for example, tertiary amine bases such as DIEA, TEA, carbonatebases such as Na₂CO₃, K₂CO₃, Cs₂CO₃, hydrides such as NaH, KH,borohydrides, cyanoborohydrides and the like, alkoxides such as NaOCH₃,and the like. The base itself may also serve as a solvent. The reactionmay optionally be run neat, i.e., without any base and/or solvent. Thesecoupling reactions are generally fast and conversion occurs typically inambient conditions. However, depending upon the particular substrate,such reactions may require heat, as appreciated by those skilled in theart.

Similarly, carbamates as illustrated in sub-schemes 5 and 1 where Nu− isan amine, anhydrides as illustrated in sub-scheme 1 where Nu− is anoxygen, reverse amides as generally illustrated in sub-scheme 8 whereNu− is an amine and E+ is an acid chloride, ureas as illustrated insub-scheme 3, thioamides and thioureas where the respective carbonyloxygen is a sulfur, thiocarbamates where the respective carbonyl oxygenand/or carbamate oxygen is a sulfur, and the like. While the abovemethods are so described, they are not exhaustive, and other methods forlinking groups A and B together may be utilized as appreciated by thoseskilled in the art.

Although sub-schemes 1-9 are illustrated as having the nucleophilic andelectrophilic coupling groups, such as the amino group and acid chloridegroups illustrated in sub-scheme 2, directly attached to the substrate,either the A group or B ring, in question, the invention is not solimited. It is contemplated herein that these nucleophilic and/orelectrophilic coupling groups may be tethered from their respectivering. For example, the amine group on the B ring, and/or the acid halidegroup on the A group or ring, as illustrated in sub-scheme 2, may beremoved from direct attachment to the ring by a one or more atom spacer,such as by a methylene, ethylene spacer or the like. As appreciated bythose skilled in the art, such spacer may or may not affect the couplingreactions described above, and accordingly, such reaction conditions mayneed to be modified to effect the desired transformation.

The coupling methods described in sub-schemes 1-9 are also applicablefor coupling desired A groups or rings to desired pyrazolo-pyridinone-Bring intermediates, such as to substituted B ring carboxylic acids(Example 2) to synthesize desired compounds of Formulas I and II. Forexample, a desirably substituted pyrazolo-pyridinone-benzoic acid maybereacted with a desirably substituted primary or secondary amine, such asan NHR⁷R⁷ or NHR⁷R⁸ group in the presence of a suitable solvent and aknown coupling reagent, such as TBTU, HATU, CDI or others, to preparethe desired A-B amide bond, and the final compound of Formulas I or II.

Note that the B-A moiety is connected through a linker “L”. “L” may beany linker generally defined by the R⁵ groups in Formulas I and II, andparticularly, it includes, without limitation, an amide, a urea, athiourea, a thioamide, a carbamate, an anhydride, a sulfonamide and thelike, allowing for spacer atoms either between ring B and L and/orbetween ring or group A and L, as described in Scheme 3 above.

The following specific examples (starting reagents, intermediates andcompounds of Formulas I and II) and methods of making compounds of theinvention are set forth. It should be appreciated that the above generalmethods and specific examples below are merely for illustrative purposesonly and are not to be construed as limiting the scope of this inventionin any manner.

While the examples described above provide processes for synthesizingcompounds of Formulas I and II, it should be appreciated that othermethods may be utilized to prepare such compounds. Methods involving theuse of protecting groups may be used. Particularly, if one or morefunctional groups, for example carboxy, hydroxy, amino, or mercaptogroups, are or need to be protected in preparing the compounds of theinvention, because they are not intended to take part in a specificreaction or chemical transformation, various known conventionalprotecting groups may be used. For example, protecting groups typicallyutilized in the synthesis of natural and synthetic compounds, includingpeptides, nucleic acids, derivatives thereof and sugars, having multiplereactive centers, chiral centers and other sites potentially susceptibleto the reaction reagents and/or conditions, may be used.

The protection of functional groups by protecting groups, the protectinggroups themselves, and their removal reactions (commonly referred to as“deprotection”) are described, for example, in standard reference works,such as J. F. W. McOmie, Protective Groups in Organic Chemistry, PlenumPress, London and New York (1973), in T. W. Greene, Protective Groups inOrganic Synthesis, Wiley, New York (1981), in The Peptides, Volume 3, E.Gross and J. Meienhofer editors, Academic Press, London and New York(1981), in Methoden der Organischen Chemie (Methods of OrganicChemistry), Houben Weyl, 4^(th) edition, Volume 15/1, Georg ThiemeVerlag, Stuttgart (1974), in H.-D. Jakubke and H. Jescheit, Aminosäuren,Peptide, Proteine (Amino Acids, Peptides, Proteins), Verlag Chemie,Weinheim, Deerfield Beach, and Basel (1982), and in Jochen Lehmann,Chemie der Kohienhydrate: Monosaccharide und Derivate (Chemistry ofCarbohydrates: Monosaccharides and Derivatives), Georg Thieme Verlag,Stuttgart (1974).

Salts of a compound of the invention having a salt-forming group may beprepared in a conventional manner or manner known to persons skilled inthe art. For example, acid addition salts of compounds of the inventionmay be obtained by treatment with an acid or with a suitable anionexchange reagent. A salt with two acid molecules (for example adihalogenide) may also be converted into a salt with one acid moleculeper compound (for example a monohalogenide); this may be done by heatingto a melt, or for example by heating as a solid under a high vacuum atelevated temperature, for example from 50° C. to 170° C., one moleculeof the acid being expelled per molecule of the compound.

Acid salts can usually be converted to free-base compounds, e.g. bytreating the salt with suitable basic agents, for example with alkalimetal carbonates, alkali metal hydrogen carbonates, or alkali metalhydroxides, typically potassium carbonate or sodium hydroxide. Exemplarysalt forms and their preparation are described herein in the Definitionsection of the application.

All synthetic procedures described herein can be carried out under knownreaction conditions, advantageously under those described herein, eitherin the absence or in the presence (usually) of solvents or diluents. Asappreciated by those of ordinary skill in the art, the solvents shouldbe inert with respect to, and should be able to dissolve, the startingmaterials and other reagents used. Solvents should be able to partiallyor wholly solubilize the reactants in the absence or presence ofcatalysts, condensing agents or neutralizing agents, for example ionexchangers, typically cation exchangers for example in the H⁺ form. Theability of the solvent to allow and/or influence the progress or rate ofthe reaction is generally dependant on the type and properties of thesolvent(s), the reaction conditions including temperature, pressure,atmospheric conditions such as in an inert atmosphere under argon ornitrogen, and concentration, and of the reactants themselves.

Suitable solvents for conducting reactions to synthesize compounds ofthe invention include, without limitation, water; esters, includinglower alkyl-lower alkanoates, e.g., ethyl acetate; ethers includingaliphatic ethers, e.g., Et₂O and ethylene glycol dimethylether or cyclicethers, e.g., THF; liquid aromatic hydrocarbons, including benzene,toluene and xylene; alcohols, including MeOH, EtOH, 1-propanol, IPOH, n-and t-butanol; nitriles including CH₃CN; halogenated hydrocarbons,including CH₂Cl₂, CHCl₃ and CCl₄; acid amides including DMF; sulfoxides,including DMSO; bases, including heterocyclic nitrogen bases, e.g.pyridine; carboxylic acids, including lower alkanecarboxylic acids,e.g., AcOH; inorganic acids including HCl, HBr, HF, H₂SO₄ and the like;carboxylic acid anhydrides, including lower alkane acid anhydrides,e.g., acetic anhydride; cyclic, linear, or branched hydrocarbons,including cyclohexane, hexane, pentane, isopentane and the like, andmixtures of these solvents, such as purely organic solvent combinations,or water-containing solvent combinations e.g., aqueous solutions. Thesesolvents and solvent mixtures may also be used in “working-up” thereaction as well as in processing the reaction and/or isolating thereaction product(s), such as in chromatography.

The invention further encompasses “intermediate” compounds, includingstructures produced from the synthetic procedures described, whetherisolated or not, prior to obtaining the finally desired compound.Structures resulting from carrying out steps from a transient startingmaterial, structures resulting from divergence from the describedmethod(s) at any stage, and structures forming starting materials underthe reaction conditions are all “intermediates” included in theinvention. Further, structures produced by using starting materials inthe form of a reactive derivative or salt, or produced by a compoundobtainable by means of the process according to the invention andstructures resulting from processing the compounds of the invention insitu are also within the scope of the invention.

New starting materials and/or intermediates, as well as processes forthe preparation thereof, are likewise the subject of this invention. Inselect embodiments, such starting materials are used and reactionconditions so selected as to obtain the desired compound(s).

Starting materials of the invention, are either known, commerciallyavailable, or can be synthesized in analogy to or according to methodsthat are known in the art. Many starting materials may be preparedaccording to known processes and, in particular, can be prepared usingprocesses described in the examples. In synthesizing starting materials,functional groups may be protected with suitable protecting groups whennecessary. Protecting groups, their introduction and removal aredescribed above.

In synthesizing a compound of formulas I and II according to a desiredprocedure, the steps may be performed in an order suitable to preparethe compound, including a procedure described herein or by an alternateorder of steps described herein, and may be preceded, or followed, byadditional protection/deprotection steps as necessary. The proceduresmay further use appropriate reaction conditions, including inertsolvents, additional reagents, such as bases (e.g., LDA, DIEA, pyridine,K₂CO₃, and the like), catalysts, and salt forms of the above. Theintermediates may be isolated or carried on in situ, with or withoutpurification. Purification methods are known in the art and include, forexample, crystallization, chromatography (liquid and gas phase, and thelike), extraction, distillation, trituration, reverse phase HPLC and thelike. Reactions conditions such as temperature, duration, pressure, andatmosphere (inert gas, ambient) are known in the art and may be adjustedas appropriate for the reaction. Synthetic chemistry transformations andprotecting group methodologies (protection and deprotection) useful insynthesizing the inhibitor compounds described herein are known in theart and include, for example, those such as described in R. Larock,Comprehensive Organic Transformations, VCH Publishers (1989); T. W.Greene and P. G. M. Wuts, Protective Groups in Organic Synthesis, 3^(rd)edition, John Wiley and Sons (1999); L. Fieser and M.

In one embodiment, the present invention provides a method of making acompound of Formula I or II, the method comprising the step of reactinga compound 7

wherein R¹, R² and R³ are as defined herein and LG is a halogen, with a

compound 8 having a general formula

wherein X is an amine, thiol or alcohol and A¹, A², A³, A⁴ and R⁵ are asdefined in Formulas I or II, to make a compound of Formula I or II.

In another embodiment, the present invention provides a method of makinga compound of Formula I or II, the method comprising the step ofreacting a compound 7a

wherein R¹, R² and R³ are as defined herein, with a compound 8a having ageneral formula

wherein X is an amine, thiol or alcohol and R⁵, R^(6a), R^(6b) and n areas defined in Formulas I or II, to make a compound of Formula I or II.

Compounds of the present invention can possess, in general, one or moreasymmetric carbon atoms and are thus capable of existing in the form ofoptical isomers including, without limitation, racemates and racemicmixtures, scalemic mixtures, single enantiomers, individualdiastereomers and diastereomeric mixtures. All such isomeric forms ofthese compounds are expressly included in the present invention. Theoptical isomers can be obtained by resolution of the racemic mixturesaccording to conventional processes, e.g., by formation ofdiastereoisomeric salts, by treatment with an optically active acid orbase. Examples of appropriate acids are tartaric, diacetyltartaric,dibenzoyltartaric, ditoluoyltartaric, and camphorsulfonic acid and thenseparation of the mixture of diastereoisomers by crystallizationfollowed by liberation of the optically active bases from these salts. Adifferent process for separation of optical isomers involves the use ofa chiral chromatography column optimally chosen to maximize theseparation of the enantiomers. Still another available method involvessynthesis of covalent diastereoisomeric molecules by reacting compoundsof the invention with an optically pure acid in an activated form or anoptically pure isocyanate. The synthesized diastereoisomers can beseparated by conventional means such as chromatography, distillation,crystallization or sublimation, and then hydrolyzed to deliver theenantiomerically pure compound. The optically active compounds of theinvention can likewise be obtained by using optically active startingmaterials. These isomers may be in the form of a free acid, a free base,an ester or a salt.

The compounds of this invention may also be represented in multipletautomeric forms. The invention expressly includes all tautomeric formsof the compounds described herein.

The compounds may also occur in cis- or trans- or E- or Z-double bondisomeric forms. All such isomeric forms of such compounds are expresslyincluded in the present invention. All crystal forms of the compoundsdescribed herein are expressly included in the present invention.

The present invention also includes isotopically-labelled compounds,which are identical to those recited herein, but for the fact that oneor more atoms are replaced by an atom having an atomic mass or massnumber different from the atomic mass or mass number usually found innature. Examples of isotopes that can be incorporated into compounds ofthe invention include isotopes of hydrogen, carbon, nitrogen, oxygen,phosphorous, fluorine and chlorine, such as ²H, ³H, ¹³C, ¹⁴C, ¹⁵N, ¹⁶O,¹⁷O, ³¹P, ³²P, ³⁵S, ¹⁸F, and ³⁶Cl.

Compounds of the present invention that contain the aforementionedisotopes and/or other isotopes of other atoms are within the scope ofthis invention. Certain isotopically-labelled compounds of the presentinvention, for example those into which radioactive isotopes such as ³Hand ¹⁴C are incorporated, are useful in drug and/or substrate tissuedistribution assays. Tritiated, i.e., ³H, and carbon-14, i.e., ¹⁴C,isotopes are particularly preferred for their ease of preparation anddetection. Further, substitution with heavier isotopes such asdeuterium, i.e., ²H, can afford certain therapeutic advantages resultingfrom greater metabolic stability, for example increased in vivohalf-life or reduced dosage requirements and, hence, may be preferred insome circumstances. Isotopically labelled compounds of this inventioncan generally be prepared by substituting a readily availableisotopically labelled reagent for a non-isotopically labelled reagent.

Substituents on ring moieties (e.g., phenyl, thienyl, etc.) may beattached to specific atoms, whereby they are intended to be fixed tothat atom, or they may be drawn unattached to a specific atom, wherebythey are intended to be attached at any available atom that is notalready substituted by an atom other than H (hydrogen). For example, incompounds of Formula II, R^(6b) moieties may be attached at anyavailable carbon atom.

p38 In-Vitro HTRF Enzyme Assay

The compounds of the invention can be tested for their respectiveaffinities for the p38 protein using a conventional p38 in-vitro enzymeactivity assay. For example, a P38-alpha HTRF assay may be used tomeasure the protein's in-vitro phosphorylation activity, and the dataanalyzed using time resolved fluorimetry techniques (FRET). A p38 HTRFassay is as follows. The kinase reaction buffer for p38α, p38β, p38δ andp38γ HTRF assays consists of 50 mM Tris-pH 7.5, 5 mM MgCl₂, 0.1 mg/mLBSA, 100 μM Na₃VO₄ and 0.5 mM DTT. The HTRF detection buffer contains100 mM HEPES-pH 7.5, 100 mM NaCl, 0.1% BSA, 0.05% Tween-20, and 10 mMEDTA. Each compound was dissolved in 100% DMSO and serially diluted (3fold, 10 point) in a polypropylene 96-well microtiter plate (drugplate). The final starting concentration of the compound in the p38α andp38β enzymatic assays was about 1 μM. The final starting concentrationof each compound in the p38δ and p38γ enzymatic assays was about 10 μM.The p38α, p38β, p38δ and p38γ kinase reactions were carried out in apolypropylene 96-well black round bottom assay plate in total volume of30 μL kinase reaction buffer. Appropriate concentration of purified andactivated enzyme (recombinant human) was mixed with indicatedconcentration of ATP and 100 nM GST-ATF2-Avitag, in the presence orabsence (HI control) of each compound. In the absence of enzyme, thebackground was measured as LO control. HI controls and LO controlscontained only DMSO. The reaction was allowed to incubate for 1 hour atRT. The kinase reaction was terminated and phospho-ATF2 was revealed byaddition of 30 μL of HTRF detection buffer supplemented with 0.1 nMEu-anti-pTP and 4 nM SA-APC. After 60 minutes incubation at roomtemperature, the assay plate was read in a Discovery Plate Reader. Thewells were excited with coherent 320 nm light and the ratio of delayed(50 ms post excitation) emissions at 620 nM (native europiumfluorescence) and 665 nm (europium fluorescence transferred toallophycocyanin—an index of substrate phosphorylation) was determined(Park et al. 1999). The resulting data was analyzed by taking theproportion of substrate phosphorylated in the kinase reaction in thepresence of each individual compound and comparing it with thatphosphorylated in the presence of DMSO vehicle alone (HI control). Thedata was calculated using the formula: % control (POC)=(compound−averageLO)/(average HI−average LO)*100. Data (consisting of POC and inhibitorconcentration in 1M) was fitted to a 4-parameter equation(y=A+((B−A)/(1+((x/C)^D))), where A is the minimum y (POC) value, B isthe maximum y (POC), C is the x (compound concentration) at the point ofinflection and D is the slope factor, using a Levenburg-Marquardtnon-linear regression algorithm. The inhibition constant (Ki) of theinhibitor was estimated from the IC₅₀ (compound concentration at thepoint of inflection C) using the Cheng-Prussof equation:K_(i)=IC₅₀/(I+S/Km), where S is the ATP substrate concentration, and Kmis the Michaelis constant for ATP as determined experimentally. Allresults were expressed as the mean±the standard error of the mean. Dataacquisition and non-linear regression algorithms were performed usingActivity Base v5.2 and XLfit software v4.1 respectively.

Lipopolysaccharide-Activated Monocyte TNF Production Assay

Isolation of Monocytes

Test compounds were evaluated in vitro for the ability to inhibit theproduction of TNF by monocytes activated with bacteriallipopolysaccharide (LPS). Fresh residual source leukocytes (a byproductof plateletpheresis) were obtained from a local blood bank, andperipheral blood mononuclear cells (PBMCs) were isolated by densitygradient centrifugation on Ficol-Paque Plus (Pharmacia). PBMCs weresuspended at 2×10⁶/mL in DMEM supplemented to contain 2% FCS, 10 mM, 0.3mg/mL glutamate, 100 U/mL penicillin G and 100 mg/mL streptomycinsulfate (complete media). Cells were plated into Falcon flat bottom, 96well culture plates (200 μL/well) and cultured overnight at 37° C. and6% CO₂. Non-adherent cells were removed by washing with 200 μl/well offresh medium. Wells containing adherent cells (˜70% monocytes) werereplenished with 100 μL of fresh medium.

Preparation of Test Compound Stock Solutions

Test compounds were dissolved in DMZ. Compound stock solutions wereprepared to an initial concentration of 10-50 μM. Stocks were dilutedinitially to 20-200 μM in complete media. Nine two-fold serial dilutionsof each compound were then prepared in complete medium.

Treatment of Cells with Test Compounds and Activation of TNF Productionwith Lipopolysaccharide

One hundred microliters of each test compound dilution were added tomicrotiter wells containing adherent monocytes and 100 μL completemedium. Monocytes were cultured with test compounds for 60 min at whichtime 25 μL of complete medium containing 30 ng/mL lipopolysaccharidefrom E. coli K532 were added to each well. Cells were cultured anadditional 4 hrs. Culture supernatants were then removed and TNFpresence in the supernatants was quantified using an ELISA.

TNF Elisa

Flat bottom, 96 well Corning High Binding ELISA plates were coatedovernight (4° C.) with 150 μL/well of 3 μg/mL murine anti-human TNF-αMAb (R&D Systems #MAB210). Wells were then blocked for 1 h at roomtemperature with 200 L/well of CaCl₂-free ELISA buffer supplemented tocontain 20 mg/mL BSA (standard ELISA buffer: 20 mM, 150 mM NaCl, 2 mMCaCl₂, 0.15 mM thimerosal, pH 7.4). Plates were washed and replenishedwith 100 μL of test supernatants (diluted 1:3) or standards. Standardsconsisted of eleven 1.5-fold serial dilutions from a stock of 1 ng/mLrecombinant human TNF (R&D Systems). Plates were incubated at roomtemperature for 1 h on orbital shaker (300 rpm), washed and replenishedwith 100 μL/well of 0.5 μg/mL goat anti-human TNF-α (R&D systems#AB-210-NA) biotinylated at a 4:1 ratio. Plates were incubated for 40min, washed and replenished with 100 μL/well of alkalinephosphatase-conjugated streptavidin (Jackson ImmunoResearch#016-050-084) at 0.02 μg/mL. Plates were incubated 30 min, washed andreplenished with 200 μL/well of 1 mg/mL of p-nitrophenyl phosphate.After 30 min, plates were read at 405 nm on a V_(max) plate reader.

Data Analysis

Standard curve data were fit to a second order polynomial and unknownTNF-α concentrations determined from their OD by solving this equationfor concentration. TNF concentrations were then plotted vs. testcompound concentration using a second order polynomial. This equationwas then used to calculate the concentration of test compounds causing a50% reduction in TNF production.

Compounds of the invention can also be shown to inhibit LPS-inducedrelease of IL-1β, IL-6 and/or IL-8 from monocytes by measuringconcentrations of IL-1β, IL-6 and/or IL-8 by methods well known to thoseskilled in the art. In a similar manner to the above described assayinvolving the LPS induced release of TNF-α from monocytes, compounds ofthis invention can also be shown to inhibit LPS induced release ofIL-1β, IL-6 and/or IL-8 from monocytes by measuring concentrations ofIL-1β, IL-6 and/or IL-8 by methods well known to those skilled in theart. Thus, the compounds of the invention may lower elevated levels ofTNF-α, IL-1, IL-6, and IL-8 levels. Reducing elevated levels of theseinflammatory cytokines to basal levels or below is favorable incontrolling, slowing progression, and alleviating many disease states.Data (IC₅₀ value ranges) for exemplary compounds of the presentinvention in this assay is provided in Table 1.

Lipopolysaccharide-Activated THP1 Cell TNF Production Assay

THP1 cells are resuspended in fresh THP1 media (RPMI 1640, 10%heat-inactivated FBS, 1XPGS, 1XNEAA, plus 30 μM PME) at a concentrationof 1E6/mL. One hundred microliters of cells per well are plated in apolystyrene 96-well tissue culture. One microgram per mL of bacterialLPS is prepared in THP1 media and is transferred to the wells. Testcompounds are dissolved in 100% DMSO and are serially diluted 3-fold ina polypropylene 96-well microtiter plate (drug plate). HI control and LOcontrol wells contain only DMSO. One microliter of test compound fromthe drug plate followed by 10 μL of LPS are transferred to the cellplate. The treated cells are induced to synthesize and secrete TNF-α at37° C. for 3 h. Forty microliters of conditioned media are transferredto a 96-well polypropylene plate containing 110 μL of ECL buffer (50 mMTris-HCl pH 8.0, 100 mM NaCl, 0.05% Tween 20, 0.05% NaN₃ and 1% FBS)supplemented with 0.44 nM MAB610 monoclonal Ab (R&D Systems), 0.34 nMruthenylated AF210NA polyclonal Ab (R&D Systems) and 44 μg/mL sheepanti-mouse M280 Dynabeads (Dynal). After a 2 h incubation at roomtemperature with shaking, the reaction is read on the ECL M8 Instrument(IGEN Inc.). A low voltage is applied to the ruthenylated TNF-α immunecomplexes, which in the presence of TPA (the active component inOriglo), results in a cyclical redox reaction generating light at 620nM. The amount of secreted TNF-α in the presence of compound comparedwith that in the presence of DMSO vehicle alone (HI control) iscalculated using the formula: % control (POC)=(cpd−average LO)/(averageHI−average LO)*100. Data (consisting of POC and inhibitor concentrationin μM) is fitted to a 4-parameter equation (y=A+((B−A)/(1+((x/C)^D))),where A is the minimum y (POC) value, B is the maximum y (POC), C is thex (cpd concentration) at the point of inflection and D is the slopefactor) using a Levenburg-Marquardt non-linear regression algorithm.Data (IC₅₀ value ranges) for exemplary compounds of the presentinvention in this assay is provided in Table 1.

For example, the active compound(s) andexcipient(s) may be tableted or encapsulated by known and acceptedmethods for convenient administration. Examples of suitable formulationsinclude, without limitation, pills, tablets, soft and hard-shell gelcapsules, troches, orally-dissolvable forms and delayed orcontrolled-release formulations thereof. Particularly, capsule or tabletformulations may contain one or more controlled-release agents, such ashydroxypropylmethyl cellulose, as a dispersion with the activecompound(s).

In the case of psoriasis and other skin conditions, it may be preferableto apply a topical preparation of compounds of this invention to theaffected area two to four times a day. Formulations suitable for topicaladministration include liquid or semi-liquid preparations suitable forpenetration through the skin (e.g., liniments, lotions, ointments,creams, pastes, suspensions and the like) and drops suitable foradministration to the eye, ear, or nose. A suitable topical dose ofactive ingredient of a compound of the invention is 0.1 mg to 150 mgadministered one to four, preferably one or two times daily. For topicaladministration, the active ingredient may comprise from 0.001% to 10%w/w, e.g., from 1% to 2% by weight of the formulation, although it maycomprise as much as 10% w/w, but preferably not more than 5% w/w, andmore preferably from 0.1% to 1% of the formulation.

When formulated in an ointment, the active ingredients may be employedwith either paraffinic or a water-miscible ointment base. Alternatively,the active ingredients may be formulated in a cream with an oil-in-watercream base. If desired, the aqueous phase of the cream base may include,for example at least 30% w/w of a polyhydric alcohol such as propyleneglycol, butane-1,3-diol, mannitol, sorbitol, glycerol, polyethyleneglycol and mixtures thereof. The topical formulation may desirablyinclude a compound, which enhances absorption or penetration of theactive ingredient through the skin or other affected areas. Examples ofsuch dermal penetration enhancers include DMSO and related analogs.

The compounds of this invention can also be administered by transdermaldevice. Preferably transdermal administration will be accomplished usinga patch either of the reservoir and porous membrane type or of a solidmatrix variety. In either case, the active agent is deliveredcontinuously from the reservoir or microcapsules through a membrane intothe active agent permeable adhesive, which is in contact with the skinor mucosa of the recipient. If the active agent is absorbed through theskin, a controlled and predetermined flow of the active agent isadministered to the recipient. In the case of microcapsules, theencapsulating agent may also function as the membrane.

The oily phase of the emulsions of this invention may be constitutedfrom known ingredients in a known manner. While the phase may comprisemerely an emulsifier, it may comprise a mixture of at least oneemulsifier with a fat or an oil or with both a fat and an oil.Preferably, a hydrophilic emulsifier is included together with alipophilic emulsifier, which acts as a stabilizer. It is also preferredto include both an oil and a fat. Together, the emulsifier(s) with orwithout stabilizer(s) make-up the so-called emulsifying wax, and the waxtogether with the oil and fat make up the so-called emulsifying ointmentbase, which forms the oily dispersed phase of the cream formulations.Emulsifiers and emulsion stabilizers suitable for use in the formulationof the present invention include, for example, Tween 60, Span 80,cetostearyl alcohol, myristyl alcohol, glyceryl monostearate, sodiumlauryl sulfate, glyceryl distearate alone or with a wax, or othermaterials well known in the art.

The choice of suitable oils or fats for the formulation is based onachieving the desired cosmetic properties, since the solubility of theactive compound in most oils likely to be used in pharmaceuticalemulsion formulations is very low. Thus, the cream should preferably bea non-greasy, non-staining and washable product with suitableconsistency to avoid leakage from tubes or other containers. Straight orbranched chain, mono- or dibasic alkyl esters such as di-isoadipate,isocetyl stearate, propylene glycol diester of coconut fatty acids,isopropyl myristate, decyl oleate, isopropyl palmitate, butyl stearate,2-ethylhexyl palmitate or a blend of branched chain esters may be used.These may be used alone or in combination depending on the propertiesrequired. Alternatively, high melting point lipids such as white softparaffin and/or liquid paraffin or other mineral oils can be used.

Formulations for parenteral administration may be in the form of aqueousor non-aqueous isotonic sterile injection solutions or suspensions.These solutions and suspensions may be prepared from sterile powders orgranules using one or more of the carriers or diluents mentioned for usein the formulations for oral administration or by using other suitabledispersing or wetting agents and suspending agents. The compounds may bedissolved in water, polyethylene glycol, propylene glycol, ethanol, cornoil, cottonseed oil, peanut oil, sesame oil, benzyl alcohol, sodiumchloride, tragacanth gum, and/or various buffers. Other excipients andmodes of administration are well and widely known in the pharmaceuticalart. The active ingredient may also be administered by injection as acomposition with suitable carriers including saline, dextrose, or water,or with cyclodextrin (ie. Captisol), cosolvent solubilization (ie.propylene glycol) or micellar solubilization (ie. Tween 80).

The sterile injectable preparation may also be a sterile injectablesolution or suspension in a non-toxic parenterally acceptable diluent orsolvent, for example as a solution in 1,3-butanediol. Among theacceptable vehicles and solvents that may be employed are water,Ringer's solution, and isotonic sodium chloride solution. In addition,sterile, fixed oils are conventionally employed as a solvent orsuspending medium. For this purpose any bland fixed oil may be employed,including synthetic mono- or diglycerides. In addition, fatty acids suchas oleic acid find use in the preparation of injectables.

The active ingredient may also be administered by injection as acomposition with suitable carriers including saline, dextrose, or water.The daily parenteral dosage regimen will be from about 0.1 to about 30mg/kg of total body weight, preferably from about 0.1 to about 10 mg/kg,and more preferably from about 0.25 mg to 1 mg/kg.

For pulmonary administration, the pharmaceutical composition may beadministered in the form of an aerosol or with an inhaler including drypowder aerosol.

Suppositories for rectal administration of the drug can be prepared bymixing the drug with a suitable non-irritating excipient such as cocoabutter and polyethylene glycols that are solid at ordinary temperaturesbut liquid at the rectal temperature and will therefore melt in therectum and release the drug.

The pharmaceutical compositions may be subjected to conventionalpharmaceutical operations such as sterilization and/or may containconventional excipients, such as preservatives, stabilizers, wettingagents, emulsifiers, buffers etc. Tablets and pills can additionally beprepared with enteric coatings. Such compositions may also compriseexcipients, such as wetting, sweetening, flavoring, and perfumingagents.
